. drawing and to the letters of reference marked thereon, which form a part of this specification.

The nature of our invention consists in the construction and arrangement of pigeon-holes in such a manner that any number of the sections or partitions may be removed at will, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which our invention appertains to make and use the same we will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a front view of a case of pigeonholes, and Fig. 2 is an enlarged View of a washer used in the same.

A represents a case of anysuitable dimensions, provided with any desired number of vertical and horizontal partitions, B B, forming pigeon-holes. V

Ordinarily, in the construction of pigeonhole cases, either the horizontal or the vertical partitions run the entire length of the case, and the spaces formed by the same divided by smaller partitions, the whole being firmly gluedtogether or otherwise permanently joined. This is especially the case with the partitions running the entire length of the case, as they are invariably firmly joined to the case. Hence, when any one partition is worn, broken, or otherwise injured so that it is necessary to remove the same and replace it by another, it is necessary to take out a large number of these partitions, and none but a cabinet-maker can do it nicely.

To obviate all this difficulty is the object of our invention; and for this purpose we make all the sections or partitions B B of the same size as the pigeon-holes desired, and unite the same by means of metal supports 0 ofthe same length as the partitions or sections. These supports are grooved longitudinally on all four sides for the insertion of the partitions; and through a hole, a, in the center of each support passes a screw-rod, fastened by a nut on one or both ends. On each end of this rod, before being screwed up, is placed a washer, D, of substantially the form shown in Fig. 2, having four points or teeth, I) b, one of which enters each of the four partitions B, so that when the rod is screwed up'the partitions or sections will be held firmly in place.

By unscrewing the desired number of rods both the lateral and vertical sections or partitions may be removed, as desired.

Having thus fully described our invention, what We claim as new, and desire'to secure by Letters Patent, is-

1. The sections B B, constructed to be used in combination with the support 0, so that the sections, both vertical and lateral, may be removed as desired, substantially as and for the purpose specified.

2. The supports 0, provided with grooves and central perforation a, for the purposes herein set forth.

3. The combination of the sections B, support 0, and washer D with points or teeth I), and the whole united by a screw-rod and nut, substantially as and for the purposes herein set forth. I

In testimony that we claim the forcgoin g as our own we affix our signatures in presence of two witnesses.
